Hello

I want to merge a radDocument in the  radDocument itself, ( Me.radRichTextBox.Document = Me.radRichTextBox.MailMerge(True)
It works fine, but doesn't insert CRLF in each page

I try to put a Page break

            Me.radRichTextBox.Document.InsertPageBreak()
            Me.radRichTextBox.Document = Me.radRichTextBox.MailMerge(True)

And a Linebreak at the end of the document

            Me.radRichTextBox.Document.CaretPosition.MoveToLastPositionInDocument()
            Me.radRichTextBox.Document.InsertLineBreak()

            Me.radRichTextBox.Document = Me.radRichTextBox.MailMerge(True)

None of the methods described above, work

Can u help us ?

Thank a lot

Anne

Hello Anne,

I am not quite sure what is the desired behavior, but here are my suggestions:

  1. If you wish to perform a mail merge and replace the current(template) document of the RadRichTextBox, you should do it as follows:
    Me.radRichTextBox.Document = Me.radRichTextBox.MailMerge(True)
    This should add section breaks between the separate records. You can ensure that by turning on the formatting symbols(from the RadRichTextBoxRibbonUI or from code using the ShowFormattingSymbols property). You should also know that in order for your records to look placed on different pages, the LayoutMode of your editor should be set to Paged.
  2. If you wish to insert the merged records in the same document instance that holds your template, you can do it like this:
    RadDocument merged = this.radRichTextBox.MailMerge(true);
    RadDocument document = new RadDocument();
    document.InsertFragment(new DocumentFragment(this.radRichTextBox.Document));
    document.InsertPageBreak();
    merged.Selection.SelectAll();
    DocumentFragment fragment = merged.Selection.CopySelectedDocumentElements();
    document.InsertFragment(fragment);
    merged.MeasureAndArrangeInDefaultSize();
    document.InsertFragment(new DocumentFragment(merged));
    this.radRichTextBox.Document = document;
Once again, the LayoutMode should be set to Paged.

I hope this answers your question. If not, please get back to us with additional information or a sample project, demonstrating the issue.

Kind regards,

I am doing multiple merges combining the output of each merge into a single document using the following code:

RadDocument templateDocument = OpenRadDocument(templateFile);
templateDocument.MailMergeDataSource.ItemsSource = mergeData;
 
RadDocument mergedDocument = templateDocument.MailMerge(true);
 
if (combinedMergeDocument == null)
{
    combinedMergeDocument = new RadDocument();
    combinedMergeDocument.LayoutMode = DocumentLayoutMode.Paged;
}
 
combinedMergeDocument.CaretPosition.MoveToLastPositionInDocument();         
 
if(!combinedMergeDocument.IsEmpty)
    combinedMergeDocument.InsertPageBreak();
 
combinedMergeDocument.InsertFragment(new DocumentFragment(mergedDocument));
combinedMergeDocument.MeasureAndArrangeInDefaultSize();


When I do the merge, the resulting merged document contains a single page for each record which is perfect.  The problem is that once I insert the merged document into the combined document, the original paging is gone and the records are now split over pages. The merge document contains 10 pages but the combined document contains 6 pages because it has started it's own paging ignoring the paging from the source document. 

If I don't set the LayoutMode of the combined document, I end up with one page.

How can I maintain the original paging when inserting into the combined document ?  

If required, I wouldn't even mind adding the pages to the combined document one by one but there doesn't seem to be document pages collection exposed that I could use to select page by page.

Thanks

Hello,

The issue you are facing seems related to the method you are using in order to create DocumentFragment. Basically, the two approaches shown in my previous post differ in the way the properties of the sections are copied when creating the document fragment instance. The first approach - using the selection, copies all properties of the sections and the page/section breaks are one of them, as opposed to the second approach (which is also the one used in your snippet).

So, in order to make your project work as per your requirments I suggest you create the DocumentFragments using the other approach - through selection. 
mergedDocument.MeasureAndArrangeInDefaultSize();
mergedDocument.Selection.SelectAll();
DocumentFragment fragment = mergedDocument.Selection.CopySelectedDocumentElements();
combinedMergeDocument.InsertFragment(fragment);
I am also attaching the project I used for testing for your reference.

When it comes to your remark that if you do not set the LayoutMode of the document to Paged, the result is a single page, this is due to the fact that the default LayoutMode is Flow. If you want to ensure that the document would be in paged mode, you should keep the property as it is.

As for a pages collection of some sort, RadDocument's element hierarchy does not contain the concept of pages. Pages are simply a representative manner and depend on the layout mode. However, in the way that the project attached is implemented, the separate mail-merge entries are actually Sections, so if you need to access them, you can do so through the appropriate API.

I hope this information is helpful! Let us know if you are experiencing other problems.

Hello Krithiga,

Tables in RadDocument cannot be the first or last element in a section. This limitation of the document model is most likely the cause of the issue you are observing. Please make sure to add paragraphs before and after your table. If you are still experiencing problems, try to provide more details on your scenario.

I hope this is useful.

Hello Petya

Thank you so much , I solved this issue , that time i used  this.View.radRichTextBox.UpdateAllFields(FieldDisplayMode.Result) but now i changed that to this.View.radRichTextBox.UpdateAllFields(FieldDisplayMode.DisplayName) now it is working perfectly.

But I am facing some other problem , I want to add custom field to the merged document , so if user drag and drop cutom fileds into it , But I dont want to save the field tags in the merged document , So Instead using InsertField, I want to place  the document Fragment from GetResultFragment directly to the document with the help of insert fragment . How can i achieve this please let me know any work around for this.

Hello Krithiga,

RadRichTextBox exposes an InsertFragment() method which allows you to insert a DocumentFragment instance at the caret position. That being said, if you can obtain or create the desired result fragment, you can insert it without adding a custom field to the document.

Hi Petya,

Using the previous tips you mention, I am still unable to create a custom merge field with a table while adding a paragraph before and after the table. 

Section section = new Section();
 
Paragraph paragraphTop = new Paragraph();
paragraphTop.Inlines.Add(new Span("TOP"));
Paragraph paragraphBot = new Paragraph();
paragraphBot.Inlines.Add(new Span("BOT"));
 
section.Blocks.Add(paragraphTop);
section.Blocks.Add(table);
section.Blocks.Add(paragraphBot);
 
document.Sections.Add(section);
 
document.MeasureAndArrangeInDefaultSize();
 
return new DocumentFragment(document);
